Worship and Servitude

وَٱعْبُدْ رَبَّكَ حَتَّىٰ يَأْتِيَكَ ٱلْيَقِينُ

And worship your Lord until there comes to you the certainty [i.e., death].

إِنَّنِىٓ أَنَا ٱللَّهُ لَآ إِلَـٰهَ إِلَّآ أَنَا۠ فَٱعْبُدْنِى وَأَقِمِ ٱلصَّلَوٰةَ لِذِكْرِىٓ

Indeed, I am Allāh. There is no deity except Me, so worship Me and establish prayer for My remembrance.

إِنَّمَآ إِلَـٰهُكُمُ ٱللَّهُ ٱلَّذِى لَآ إِلَـٰهَ إِلَّا هُوَ ۚ وَسِعَ كُلَّ شَىْءٍ عِلْمًا

Your god is only Allāh, except for whom there is no deity. He has encompassed all things in knowledge."
